Diaries, photos and testimonials tell the heart wrenching stories of human suffering at the hands of the Japanese during World War Two.

In 1937, Japanese soldiers killed more than three hundred thousand people in China's former capital, Nanjing. Many were unarmed soldiers and civilians. Over twenty-thousand women were sexually assaulted and raped. The city was looted and more than a third of all of Nanjing's buildings were destroyed. In 2014, China's top legislature designated December the 13th as National Memorial Day for Nanjing Massacre victims, in order to remember those who lost their lives and expose Japanese war crimes. One year later, historical documentation about the massacre was included in UNESCO's Memory of the World Register.  It's believed there are fewer than 100 survivors alive today, who can still provide first-hand accounts of Japanese war crimes committed in Nanjing.
